"The LEO is substantial to say the least. It was developed by a guy named Don Lewis from the San Francisco area, and basically consists of a Hammond B-3, 4 Oberheim SEM's, 2 ARP 2600 modular units, 2 patch bays, Roland RE-201 and DC-50 for effects and a Revo speaker box w/ controller. Everything is encased in 1" thick acrylic and should never be moved by less than 6 people. It is, simultaneously, a work of exceptional ingenuity and unmitigated, cumbersome construction. It is, without question, the most obvious reason for the creation of MIDI." :)

Note the
Museum of Making Music will be hosting a
Moog exhibit (Moogseum) with
The Bob Moog Foundation beginning September 2009. You can find previous posts on the Moogseum
here.
Update: "The LEO is on permanent display here as well as a small selection of analog and digital synthesizers (Roland D-50, DX-7, Korg M-1). There are certain exhibits that are brought in on a temporary basis. The Moog Exhibit will be that kind of exhibit. But we also have 6 galleries of musical instruments dating all the way back to the late 1800s. All instruments are viewable to the public, but most are not playable. I will be consulting on a redesign of our Gallery 5 (The synth/80s room) after our current slide guitar exhibit is finished in April. I found out that our curator is housing several synths in an off-site warehouse including a WASP, a GNAT, and a SPIDER sequencer, a Synthi e, and a Korg Polysix just off the top of her head! So we're going to make the synth display shimmer in April."
